SPECIFICATION forming part of Letters Patent No. 79l.,OO9, dated July 4, 1905,

Application liled September '7, 190e. Serial No. 223,573.

le it known that l, .lAoon A. llmncnnaok, a citizen ol the United States, residing' at Newark, in the County olE lacking' and State el Ohio, have invented new and uselul lml'novenients in Surjlailee Uultiyators, ol whieh the Following' is a speeilieation. A

lVly invention relates to improvements `in ou l ti \i'ators,more particu larly for su r taee work or cultivation.

hiaid invention has for its object to provide tor the read,Y adjustment ot' the maohine For transpoi-tation or el'l'eetiye aetion and to promote convenience and laeility o'l olnn'ation; and to these ends it consists ol (.:ertain struetural lir-atin'es, sulgistantially as hereinafter more fully diselosml, and particularly p inted out by the claims.

lu the aoeonlpai'iying'drawing's, illustrating' the ln'elerrod embodiment ol my invention, lliigure i. is a side elevation thereof with the parts shown in 'l'ull lines in inoperative posi tion, as when transiu'n'ted t' rom plaee to plaee, and in dotted lines as when in use. Fig'. 2 is a plan View ol the same. ltig'. is a vertieal eross-seetion ol said invention.

tu the carrying' out of my invention lV provide a reaeh 1, preferably of the construetion shown, being' substantially two longitudinal members or bars l", united or bolted eonipaetly together throughout the greater portions olt their lengths, with their end por` tions spread apart.

Axle." 2 2"' bear the forward single or easter wheel 3 and the rear wheel 3", respeetivoly, one being; carried by the s]n'ernl-:u'iart lorward end portions o'l the reach l and the other secured to preferably lateral or rightangled extensions or terminals 4" ol the lower ends ol' the vertii'ziiil parallel members lf" olE a handlever ft. @laid lever has its said parallel members tl preferably brought more elosely together about at their mid-lengths than are their lower portions, said parallel mei'nbers receiving' therebetween and having' pivotal Connection with the central Shovel or plow beam 5 about at that point and like eolmeetion larther down with the spread-apart rear ends ol the reach i, said beam being' extended lorward into the draft-bar 5X. lhe latter connectionmv'. n., between the lover it and reaeh Yl wis made by a pin (j, inserted through the parallel members 47" ol' the lever -l and said rear end portions of said reaeh. t'aid members are provided with holes 'T to permit olf the adjustment oi said point of eonneetion as oeeasion or eirelunstam'zes may require. A standard or yoke 8 has the lower ends olE its members secured to the forward wheelaXle and the correspondine' ends ol' the lorward sm'ead-almrt ptn'tions ol' the reach l, and whieh yoke is suital; ly pivoted to the draft-bar extension 5X ol said plow-beam 5, the last named passing' through said yoke to hold said yoke in upright position, as disclosed by Fig'. l, the otherwiseol 1struetine' lateral plow or shovel beam being' broken away lfor that purp se.

A, quadrant-shaped bar or arm El, having' its lower end suitably piyoted or (,:onneeted to the reaeh l, about midway thereol', extends upward through and is guided by the yoke or standard S and has a plurality ol' adjusting'dioles il" therellirough, any one ol -whieh may receive a piu lll, inserted tl'u'fuurh registering' perlorations or holes ll in said yoke at its upper end to permit ot the variable :uljustment o1 the parts, as in bringing' the plows into or putti ng' them out olA operation, and amording'ly holdine'said parts when so adjusted.

l'leem'ed lati-wally oi" and to the eentral plow or shovel beam 5 are two additional plow or shovel beams 5"', with their euryed rear end portions extending' to points beyond the eorresponding' portion of said central beam. rlimilarl y arranged to said beams Fi are two lurtlun' [dow-beams 5", with their lorward ends suitably pivoted or eonneeted to said central beam, so as to permit them to be moved laterally or horizontally, as may be required, said plow-ljieams having' lixed or dopeudine' thereliron'i supplemental beams or standards 5m, whose shovels aid the plowing' or cultivating' action. riaid plow-beams have suitably eonneeted thereto arms or bars 5", and seeured to the Lipper edge ol' the eentral beam 5 is a keeper or yoke 5, reeeiyine' said arms, held therein by a set or holding' serew 5" to permit the requisite adfustment ol said ICO plmv-beams. Suitable handles 11, applied to the central beam in the usual way, are provided lor controlling the movement ol the cultivator.

lt will be noted that the plow-beams being in the dotted-line position et Fig. 1, when oi course the rear wheels will be elevated, by grasping and suitably actuating the handlever or moving it lorward the reach l may be so adjusted as to permit the lowering et' said rear wheels, thus elevating the plows or shovels out o'li contact with the surface or ground, as required or convenient for the removal or transportation et' the cultivator Vfrom place to place. With this movementor actuation of the hand-lever the quadrant-bar and its guidingyoke are caused to assume the position indicated in dotted lines in Fig. 1, which they are caused to maintain by suitably placing a holding-pin inthe requisite one ot the holes 9 of said quadrant-bar, said pin having been previously renioved from the holes l1" in the standard or yoke S, and after said adjustment of parts reinsertcd through the latter holes to permit said pin to be passed through said requisite hole. In order to restore said parts to their initial position, as in bringing the shovels or plows into eliective position or contact with the ground, the holding-pin i() having been withdrawn, the hand-lever is moved into the dotted-line position, as in Fig. l, &c., thus providingforthe elevating` et' the rear end of the reach l with the corresponding wheels, accordingly lowering the shovels or plows. 'lhe holding-pin lO is reinserted through the holes 11 of the yoke 8 and the registering; one of the holes 9 ot' the quadrant-bar, thus securing the parts in eliective or operative position.

Latitude, it will be understood, is allowed as to details herein, as they may be changed as circumstances suggest without departing from the spirit ol my invention.

I claimfl. A cultivator, employing a reach, carrying the forward wheei-axle, a yoke pivote/d to the draft-bar andthe Forward axle, means ell'ecting adjustable connection between said yoke and reach, and a hand-lever connected to the rear wheel-axle and to said reach, at its rear end, and suitably pivoted in position.

Q. A eultivator, employing a reach carrying the forward wheel-axle, a yoke pivoted to the draft-barand the Yforward axle, aquadrant-bar pivoted to said reach, about at its mid-length, and passing through said yoke, means lior ei'l'ecting adjustable connection between said quz'idrant-bar and yoke, and a hand-lever connected to the rear wheel-axle and to said reach, at its rear end, and suitabiy pivoted in position.

3. A cnltivator, employing a reach carrying the forward wheel-axle, a yoke having registering holes therein pivoted to the drait bar and the forward axle, a quad rant-barhaving a plurality of ai'ljusting-holes and guided within said yoke, and adjusting-pin engaging the holes in said quadrant-har and yoke, and a hand-lever connected to the rear wheel-axle and to said reach, at its rear end, and suitably pivoted in position.

LL. A cultivator, employing a reach carrying the forward wheel-axle, a yoke having registering holes therein and pivoted to the draft-bar and the forward axle, a seriallyperforated quad rant-bar, an adj Listing-pin for connecting said yoke and fiiuadrant-bar, and a hand-lever having its lower end connected to said rear axle, and pivoted to the central shovel-beam.

In testimony whereof l have signed my name to this specilication in the presence of two subscribing witnesses.
